A Generalized Definition of the Fractional Derivative with Applications [PDF]

open access: yesMathematical Problems in Engineering, 2021
A generalized fractional derivative (GFD) definition is proposed in this work. For a differentiable function expanded by a Taylor series, we show that

A Threshold for Quantum Advantage in Derivative Pricing [PDF]

open access: yesQuantum, 2020
We give an upper bound on the resources required for valuable quantum advantage in pricing derivatives. To do so, we give the first complete resource estimates for useful quantum derivative pricing, using autocallable and Target Accrual Redemption ...

Changes in land use are associated with the accumulation of soil phytolith-occluded organic carbon

open access: yesEcological Indicators, 2023
Organic carbon occluded in phytoliths is extremely stable and plays important roles in long-term preservation of soil and stable carbon sequestration in terrestrial ecosystems.

A Caputo fractional derivative of a function with respect to another function [PDF]

open access: yesCommunications in nonlinear science & numerical simulation, 2016
In this paper we consider a Caputo type fractional derivative with respect to another function. Some properties, like the semigroup law, a relationship between the fractional derivative and the fractional integral, Taylor’s Theorem, Fermat’s Theorem, etc.

Derivators, pointed derivators and stable derivators [PDF]

open access: yesAlgebraic & Geometric Topology, 2013
We develop some aspects of the theory of derivators, pointed derivators, and stable derivators. As a main result, we show that the values of a stable derivator can be canonically endowed with the structure of a triangulated category. Moreover, the functors belonging to the stable derivator can be turned into exact functors with respect to these ...
